R.W. Baird’s William Power this morning offers his weekly roundup of sales checks at retail regarding mobile device sales, in this case, tablet computers.

Power writes that he spoke with reps at Best Buy and Staples stores about which tablet computers they’re recommending and which ones seem to be moving units.

Apple‘s iPad “was the most popular device according to reps we spoke with,” he writes, while the Amazon.com Kindle Fire and Samsung Electronics‘s “Galaxy Tab” line of tablets were also “frequently cited alternatives.”
